UNITED STATES JOHN LAVERNE FOUST, OF BAKER, MONTANA.

ENGINE MANIFOLD.

Application filed June ,9, 1924. Serial No. 718,930.

To all whom it may concern:

Be it known that 1, JOHN LAVERNE Fo'os'r, a citizen of the United States, residing at- Baker, in the county of Fallon and State of Montana, have invented new and useful Improvements in Engine Manifolds, of which the following is a specification.

This invention relates to internal combustion engine parts and has for its object the provision of a novel manifold so constructed and arranged as to break up the spray or globules of fuel by an automatic centrifugal action whereby to insure the passage of only light vapor into the engine so as to improve the running thereof and economize on fuel.

Another object is the provision of a manifold equipped with an inlet for air or the like for directing the mixture and assisting the whirling movement.

An additional object is the provision of a device of this character which will be simple and inexpensive in manufacture, easy to install, positive in action and a general improvement in the art.

lVith the above and other objects and advantages in view, the invention consists in the details of construction and arrangement of parts to be hereinafter more fully described and claimed, and illustrated in the accompanying drawing, in which:

The figure is an elevation, partly in section, illustrating the invention.

Referring more particularly to the drawing I have shown a manifold having a ringdike central or intermediate portion 1.0 which is of course, tubular or hollow and which is formed at one side with an ex tension 11 substantially tangential to the ring portion 10 and which terminates in a coupling flange 12 adapted to be secured to the flanged outlet A of a carburetor, not shown. I

Taking off from the inner side of the ringlike central portion 10 and formed integrally therewith is an outlet pipe portion 13 necessarily under-lying or over-lying the upper portion of the ring-like center and leading to or terminating in the usual T shaped head 14 adapted for connection with an engine at the intake ports thereof in the usual manner.

' In the operation, mixture is drawn from the outlet A through the extension 11 into the ring-like body 10 and will whirl about therein, the lighter portion passing out through the pipe portion 13 into the head la and into the engine. The heavier mixture or vapor which is not properly broken up will remain close to and travel along the outer wall of the ring-like body until it passes the inrushing stream entering through the extension 11. The impinge ment of the fresh stream against this heavier vapor will break it up so that the whirling movement continues, all the mixture will eventually be broken up into a light and high explosive condition.

As an added feature, I may provide an inlet tube 15 extending into the upper portion of the ring-like body 10 for the purpose of permitting a blast or current of cool or hot air, or steam from the radiator, to enter the ring-like body 10 and not only assist the movement of the mixture therein but also dilute the same for saving fuel. The tube 15 is equipped with a suitably controlled valve 16 and may have connection with a conducting tube 17 leading from the radiator, an air heating drum or other device.

While I have shown and described the preferred form of the invention it is to be understood that I reserve the right to make such changes in the construction as will not do part from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim 1. An engine manifold comprising a hollow ring-like body formed with an extension at one side constituting a mixture inlet, and an outlet pipe portion leading from the inside wall of the ring-like body and constituting an outlet, and an auxiliary air inlet tube extending through the outer wall of the body and pointing in the direction of flow of mixture through the body.

2. An engine manifold comprising a hollow ring like body formed with an extension at one side constituting a mixture inlet and formed with an outlet portion leading from the inside wall of the ring like body at a point substantially diametrically opposite the inlet to define an outlet, and means extending intothe hollow body for positively producing a current therethrough auxiliary to the current entering said inlet.

In testimony whereof I aflix my signature.

JOHN LAVEBNE FOUST.
